San Diego  A former San Diego police officer who became the ninth department member to come under investigation in recent months for alleged misconduct pleaded not guilty Friday to four felony charges — oral copulation under color of authority, rape under the color of authority, assault and battery by an officer and false imprisonment.

How to report police misconduct

Hotline: (619) 531-2672

San Diego police have created a 24-hour hotline for the public to report officer misconduct. Calls can remain confidential and will be reviewed by Police Chief William Lansdowne daily.

The hotline is part of the chief’s seven-point plan to curb misconduct cases.

Daniel Dana, 26, is accused of texting a prostitute he had met on the job a few weeks ago and then threatening to send her to jail if she did not have sex with him early Wednesday.

The woman told police that she and Dana then went to Presidio Park in Old Town and had sex.

Dana faces up to 17 years and four months in prison if convicted of all charges, said Deputy District Attorney Annette Irving.

Brannigan ordered Dana to turn in a personal gun he keeps at his Escondido home. He told the judge his service weapon had already been taken from him.

Since news of his arrest, police have received “a few” calls from other women alleging inappropriate or off-color behavior by Dana during past interactions with him, but nothing that rises to a criminal level, police Lt. Andra Brown said Friday. Details of the reports were not released but were being investigated.

One of those women wrote in an online post Friday that Dana had pursued her for awhile. It was unclear if the alleged advances occurred while he was on or off duty.

“He really didn’t do much except aggressively hound me to ‘hook-up’ with him and kept putting his hands all over me until it got uncomfortable and I told him to get a life... sent me inappropriate text messages in the middle of the night for months and months until he finally went away...” the woman wrote.

She reported the conduct to police Friday after hearing of Dana’s arrest, she wrote. Reached by phone, the woman declined to be interviewed by The San Diego Union-Tribune.

Dana, who joined the force in 2007, is no longer a member of the Police Department, authorities said. Police said they could not disclose if he resigned or was fired.

The rape allegations came to light about 3 a.m. Wednesday when the woman called police upon returning home to Vista. The report was made several hours after San Diego Police Chief William Lansdowne publicly apologized for his officers’ alleged bad behavior and outlined a plan to curb future misconduct.

The chief said Dana and his patrol squad at Western Division had also received a talk from their sergeant at the beginning of their shift that day about the spate of misconduct and the importance of not sullying the badge. A captain had given a similar talk to the group a few weeks earlier.

Lansdowne said there had been no prior complaints against the officer.

Dana, a former Camp Pendleton Marine, is married and his wife is expecting their first child.
